Specification of Letters Patent.

Application filed February 16, 1911.

Serial No. 609,027.

To all whom it may concern:

Be it known that I, GEORGE B. GARDNER, residing at I-Iaverhill, in the county of Essex and State of Massachusetts, have invented an Improvement in Guards for Heel- Scouring Machines, of which the following is a specification.

This invention relatesto certain improvements in guards for heel-scouring machines, and more particularly to guards which are adapted to protect the upper and sole edge in front of the shank when scouring the portion of the side of the heel adjacent the breast, during which operation the forepart of the shoe is swung down beneath the scouring-wheel. While devices of this character have been produced they have not been adapted, so far as I am aware, for all conditions which are likely to arise, and are, furthermore, not adapted to be conveniently attached to the machine.

The object of my invention is to produce a guard of the above described character, which is adapted to be readily secured to the hood which is usually provided to receive the dust from the scouring-wheel, and

usually incloses the wheel on all sides except directly in front, which is further adapted to be adjusted to all positions in which a device of this sort is likely to be used, and which is of simple and inexpensive construction, so that it may be manufactured at small expense. I accomplish these ob jects by the means shown in the accompanying drawing, in which,

Figure l is a plan view of a guard and its holder made according to my invention. Fig. 2 is a front elevation thereof. Fig. 3 is a side elevation, partly in section, on the line 33, of Fig. 1. Fig. 4 is a similar view showing a different adjustment of the device, and Figs. 5 and 6 are, respectively, front views showing the device adjusted for a transversely convex wheel.

In the drawing a indicates the metal hood of the machine in which the shaft I), carrying the bufling or scouring-wheel c is mounted, said hood inclosing the wheel on all sides except the front. These wheels, in practice, are made in various forms, according to the shape of the heels to be scoured, that is, a wheel which is practically fiat transversely, is used when a straight sidedheel is to be scoured, While a wheel which is convex transversely is used when a heel having a convex side is to be scoured.

According to my invention I provide a holder or bracket d having a pair of arms (Z, a, which extend divergently therefrom and are bent, or cast in U-form, so that they may be placed astride the edge portion of the hood a and the holder (Z may extend horizontally into the hood when placed in position thereon. Set-screws e are provided in the ends of said arms, which are adapted to be screwed against the outer side of the hood. and a set-screw f is also provided in the main part of the holder 65, which is ar ranged oppositely to the set-screws e, and at one side of a straight line therebetween, and is adapted to be screwed against the inner side of the hood, as shown in Figs. 1 and 2, so as to clamp the holder securely on the hood. A round arm or rod 9 is rigidly mounted in the rear end, or the opposite end of the holder cl from its arms cl, J and extends approximately at right angles thereto, and the space between the U-shaped portions of the arms d is made materially greater than the thickness of the hood, so that, by adjusting the screws 6 and f, that is, loosening one and tightening another, said rod 9 may be held in a position parallel to the shaft 6 of the scouring-wheel.

A clip 71 is mounted on the arm g, a hole being provided therein, through which arm 9 passes, so that said clip may be moved longitudinally and rotatably on said arm. The end of the clip is split by a slot 71' which leads into said hole and a thumb screw 2' is threaded in one side of the split portion thus formed, so that said portions may be drawn together to clamp the same firmly upon the arm 9 in any position de sired, and may be loosened, sufficiently to permit the clip to be adjusted freely, or to provide a desired frictional engagement.

A. round shank is provided which passes through a hole provided therefor in the clip h at right angles to the supporting arm and at a short distance beneath the same, and the lower end portion of the clip h is also provided with a notch h which passes from the lower end thereof into the hole which receives the shank j, a thumbscrew is being provided which is threaded into one side of the split portion thus formed, so that the sides of said portion may be clamped against said shank j to hold it in the position in which it may be adjusted.

A guard-plate m is provided which is con- Patented June 11, 1912.

the guard is adjusted in a horizontal position, as shown in Fig. 2.

VVhen adjusting the above described dev1c'e to the position desired, the holder (1 is secured to the hood, so that its arm 9 is parallel to the shaft 5, and at a suitable distance therefrom, as before described, and then the clip 72, is slid horizontally of said arm, and swung thereon, so as to bring the guard m into the desired position beneath the wheel. The shank is then adjusted longitudinally in the bracket h, and by swinging the clip h into different positions and by moving the shank j longitudinally the guard may be adjusted to any position desired beneath the wheel. The shank is rotatably adjustable, as well as longitudinally slidable in the clip h, so that the guard may be tilted to one side, as indicated in Fig. 5. This is especially useful when a convex surfaced scouring-wheel is employed, as shown in Fig. 5, as the guard may be adjusted at an inclination close to the surface of the wheel adjacent the edge of the abrading surface.

The raised flange m serves to protect the shoe from the edge of the abrasive material which is used on the wheel, without interfering with the work of the operator, when he moves the shoe to scour the front portion of the side of the heel, as indicated in Fig. 3, the damage sometimes caused in this way, and which is prevented by this flange m, being particularly great. Then the operato-r wishes to change the abrasive cloth on the wheel, he merely has to push the guard downwardly, as indicated in the dotted posit-ion of Fig. 3, the clip h swinging on the arm g, and when the abrasive cloth has been placed in position the guard may be moved up again into operative position, without at any time loosening or tightening the screw 2',

as by properly adjusting said screw 2' a frictional engagement between the clip h and the arm 9 may be caused, which is suflicient to hold the parts in the various positions to which they may be moved.

The device may be applied to the opposite side of the hood from that shown, by

merely reversing the position thereof and inserting the shank j into the clip h from the opposite side. From the foregoing description it will also be seen that the guardplate may be universally adjusted, within certain limits, and may be held in any position desired with relation to the under side of the scouring-wheel.

I claim e 1. A guard for heel-scouring wheels comprising a bracket having a supporting arm adapted to be held parallel to the shaft of the machine, a clip through which said arm extends, said clip being rotatably and longitudinally adjustable on said arm, an elongated shank mounted in said clip and extending therethrough at right angles to and at one side of said arm said shank being longitudinally and rotatably adjustable therein, and a guard plate mounted on one end of said shank extending longitudinally thereof and adapted to be held beneath and adjacent the scouring wheel, substantially as described.

2. In combination with a heel-scouring wheel having an inclosing hood, a bracket having a Ushaped arm adapted to be placed astride the edge of the hood, and having oppositely disposed set-screws for clamping the same thereon and adjusting the same to different inclinations with relation thereto, a supporting arm rigidly mounted in said bracket at an angle thereto, a clip adjustably mounted on said arm and a guard plate having a shank adjust-ably mounted in said clip at an angle to said arm, said guard being adapted to be held adjacent the scouring wheel to 'cover a portion thereof, substantially as described.

3. A holder for a heel-scouring wheel guard comprising a main body portion having a U-shaped portion at one end, a pair of set-screws arranged in said portion adjacent the end thereof to clamp a support therebetween, a set-screw'in said bodyportion arranged oppositely to the set-screw 0 said end portion, an arm extending from the opposite end of said body portion at an angle thereto, and a guard plate mounted for universal adjustment on said arm, substantially as described. I

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
